I need to add some limit/home switch's to my machine, what are the best switch's and mounting arrangement to go for so that I get decent accuracy when homing / referencing the machine and also whats the best way to wire them for mach3?

I have read the mach3 instructions and it says that wiring them all in series will work but not so sure as I have not tried it, surely wiring each one indepently to an input would be better but I presume that would need another LPT connector.

Well.......?
